GigaPan is a collaborative project of the Carnegie Mellon Robotics Institute and NASA. To produce these images, a rotating robotic platform is attached to a digital camera that takes a series of photos, which are then stitched together with a unique software. SI's Fred Vuich used the technology to produce these photos from Augusta National.
